Inter Dominion Trotting Championship

A meeting with leading Australasian harness racing officials led to a decision that the Inter Dominion Trotting Championship would be discontinued after 2012.

Several new major trotting races have been created to replace the series, most notably the Great Southern Star at Melton in March, which was to be run with a one-day heat and final format.

[11][12] The Grand final was won by the prior year's victor, Just Believe: Second was Mufasa Metro (trained and driven by John Justice) and Queen Elida was third (Brent Lilley and Chris Alford) as she had been in 2022.

New Zealand's sole entrant in the 2022 series Bolt For Brilliance was withdrawn after suffering a fractured pedal bone, pulling up lame following his second place in his final heat.

[27] 2019 Rowe Cup winner Sundees Son initially led the Inter Dominion Rankings for Trotters but was withdrawn in October 2019.

After the first night trainer, Andy Garth, withdrew Mclovin due to a viral infection causing leg swelling.

The Grand final (2700m) held on 14 December was won by Winterfell (Mark Purdon) in 3:21.6 (mile rate - 2:00.1) from Majestic Man (Brad Williamson) and Massive Metro (Todd Mitchell).
